VOC Chek 575 Series Passive Samplers for ppm-Level VOCs

The Passive Sampler for Organic Vapors collects organic vapors without the use of a pump. The sampler is validated for short-term and eight-hour sampling and 24-hour indoor sampling for some compounds. Use the sampler to test exposure to VOCs such as toluene, tetrachloroethylene, trichloroethylene, xylenes, ethylbenzene, 2-butanone (MEK), hexone (MIBK), benzene, butyl acetates, and styrene. Models exclusive for ethylene oxide and methanol are also available.

Specialty samplers available for ethylene oxide (EtO), styrene, and methanol

Validated in OSHA methods as a reliable alternative to active sampling

Variety of samplers available

Only SKC offers a choice of sorbents to better target specific contaminants

Proper sorbent selection means no reverse diffusion

Superior collection efficiency

SKC sorbents have a larger surface area for higher capacities

Samplers contain > 300 mg of sorbent much
more than other brands

Meet ASTM D6246-08 and ANSI/ISEA 104-1998(r 2009) standards

575 Series Passive Samplers are now
VOC Chek 575 Series!

SKC VOC Chek 575 Passive SamplersMiniature VOC Chek 575 samplers collect organic vapors
without the use of a pump. Individual chemicals simply diffuse from
the atmosphere into the sampler at a fixed rate. SKC has scientifically
validated the sampling rate of the VOC Chek 575 Series passive samplers along
with other critical sampling parameters to meet OSHA/ASTM/ANSI requirements.
SKC VOC Chek 575 Series Passive Samplers are identified as a viable alternative
to active sampling in seven OSHA methods.

Full-shift Sampling with only ONE sampler

The Methanol Passive Sampler collects methanol for up to an 8-hour work shift with superior efficiency. The Methanol Passive Sampler overcomes the short sample times and sample migration concerns of active methods. These samplers are ideal for use in chemical, fuel, wastewater, and hydraulic fracking industries.

Validation
Passive sampling is quite different from active sampling with sorbent
tubes. With this fact in mind, NIOSH established validation protocols
for evaluating the performance of passive samplers. 1 Protocol
validation was developed so that manufacturers could produce passive
samplers that reliably assess airborne levels.

For compliance sampling, it is recommended that only passive samplers with full or bi-level validation be used. Passive samplers with lower levels of validation may be used only if verified by validated sorbent sample tube methods.

The most volatile member of a related (homologous) series of chemicals has passed full validation; therefore, related less volatile series members require only partial validation to achieve the same level of sampling accuracy (see Guild et al. [DOI: 10.1080/1047322X.1992.10390161] or request a copy from SKC).

This calculation of a sampling or uptake rate uses the diffusion coefficient of a specific chemical (D) and the cross-sectional area (A) and length (L) of the sampler’s diffusion path (based on sampler geometry).
